Interface BinaryOperator<T>
- Type Parameters:
T- the type of the operands and result of the operator
- All Superinterfaces:
BiFunction<T,T, T>
- Functional Interface:
- This is a functional interface and can therefore be used as the assignment target for a lambda expression or method reference.
Represents an operation upon two operands of the same type, producing a result
of the same type as the operands. This is a specialization of
BiFunction for the case where the operands and the result are all of
the same type.
This is a functional interface
whose functional method is BiFunction.apply(Object, Object).
